Referring to Scenario 14-15, which of the following is the correct null hypothesis to determine whether there is a significant relationship between percentage of students passing the proficiency test and the entire set of explanatory variables?

		H0: β1 = β2 = 0
		H0: β0 = β1 = β2 ≠ 0
		H0: β0 = β1 = β2 = 0
		H0: β1 = β2 ≠ 0
